UNITED STATES PATENT OFFICE;

WILLARD OOMEY, OF WESTBORO UGH, MASS, ASSIGNOR TO THE IMPROVED SOLESEWING MACHINE COMPANY, OF THE STATE OF MAINE.

BOOT AND SHOE SEWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 250,647, dated December13, 1881. Application filed J une 27, 1881. (No model.)

To all whom it may concern Be it known that I, WILLARD (JoMEY, a citizenof the United States, residing at Westborough,in the county of Worcesterand State of Massachusetts, have invented certain Improvements in Bootand Shoe Sewing Machines, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,making part of to this specification, in which Figure 1 is a sideelevation of a boot and shoe sewing machine having myiinprovementsapplied'thereto. Fig. 2 is a front elevation ofthe same. Fig. 3 is aperspective view of a por- 1 tion of the front of the machine. Fig. 4 isa horizontal section on the line m x of Fig. 2; Fig. 5, sectionaldetail.

My invention has for its object to facilitate the operation of sewingwelts to the inner soles of boots and shoes, and at the same time tokeep the edge of the welt along its entire length at a uniform distancefrom the vamp or upper, thus insuring perfect work and avoid= ing thenecessity of close attention on the part of the operator in guiding thewelt, as would be required ifit was laid by hand.

To this end my invention consists in a sliding bar or pressure device,the lower end of which is brought down into contact with the 0 welt andthen moved in such a manner as to press the welt outward from the soleagainst a guide-roll placed opposite thereto, and provided with twoflanges, between which the welt passes, and bymeans of which it iskeptin its proper position, the periphery of the lower flange serving asa gage or rest against which the boot or shoe is pressed by theoperator, while that portion of the roll located between the flangesserves as a gage or rest for the edge of the welt, which, by beingpressed constantly against it by the sliding bar, is thus keptthroughout its entire length at a uniform distance from the vamp restingagainst the edge of the adjacent flange.

My invention also consists in certain details of construction, ashereinafter set forth and specifically claimed.

In the said drawings, A represents the framework of the machine, whichis supported, as

usual, on a column or standard, 13, having a suitable base. (Not shown.)

D represents the movable work-supporting horn, which is provided withthe usual rotating whirl for laying the waxed thread in the hook of theneedle.

present invention, will notbe further described.

To the oscillating frame G, which carries the needle-bar b and cast-offbar (I, is screwed a vertical spring-bar, H, which slides in thedirection of its length in guides g hon the frame G, and is held withinthe bifurcated guide It by means of a screw, 10, passing through a slot,it, there being sufficient friction between the guide hand the bar tohold the latter in any position in which it may be left. The lower endof this bar H, which is bent into the form seen in Figs.1 and 2 to bringit over the edgeofthe tip of the horn D, is preferably provided with aremovable sharp-pointed projection, z, adapt- 7 5 ed to penetrate ashort distance into the surface of the welt I, Figs.3 and 5, on thedescent of the bar; but the lower end of this bar H maybe serrated orroughened orotherwiseconstructed to prevent it from slipping upon thewelt when pressed down firmly thereon.

In the operation of sewing the welt to the inner sole, N, as theneedle-bar b is carried down by the connecting-rod K attached to thecrankl an adjustable projection, m, on the rod K strikes against thefree end of a stiffflat spring, 19, secured to the bar H, which is thuscarried down, during the latter part of the descent of the needle, untilits projection i is brought into contact with and penetrates the welt,and as soon as the needle has ascended above the tip of the horn and thepresser-foot e is raised from off the surface of the work the frame G isoscillated with the needle in the usual manner to produce the feed,carrying with itthelower end of the spring-bar H, the lateral movementof which causes its beveled edge 15 to travel in contact with thewedge-shaped or inclined face 16 of an adjustable piece, q, attached tothe stationary block through which the presser-f'oot bar fslides, andthus, as the lower end of the bar H is moved laterally by the frame G,it is carried inward, against its own tendency to spring outward, by thewedge or inclined face 16 in an oblique direction, which causes it topress the welt I outward from the sole N and keep its edge 17 constantlyin contact with the central portion, 18, of a rotating guide-roll, M,which is supported on a stud, r, projecting down vertically from a baror arm, L, pivoted to the frame-work at s and made adjustable by meansof a screw, t, passing through a slot, u. The guide-roll M is providedwith two flanges, 'v to, between which the welt passes, and by means ofwhich it is kept down upon the sole N, the periphery of the lowerflange, w, serving as a gage or rest, against which the upper of theshoe is pressed by the operator, and consequently, as the upper is keptagainst the edge of the flange w and the outer edge,

17, of the welt is kept constantly against the smaller central portion,18, of the roll M, as seen in Fig. 5, by the oblique pushing movemeut ofthe bar H, the outer edge of the welt is always maintained at a uniformor unvarying distance from the vamp or upper, as desired, and allliability of imperfect work being produced is thus avoided. After thefeed has taken place the presser-foot e is again brought down onto thework, and as the needle continues to rise an adj ustableblock orprojection, 12, on the cast-off bar at is brought into contact with anadjustable projection, 13, Fig. 1, on the inner side of the bar H, whichis thus raised. during the latter part of the ascent of the needle-bar,and simultaneously with this upward movement the frame G is oscillatedback to its original position, which allows the bar H to spring out andfollow the inclined face 16 of the piece g, which brings it back to theposition from which it started, ready to again descend onto the welt andpush it outward as before.

By causing the projection on the rod K to strike against a stiff spring, 17, instead of against arigid projection on the bar H, the latter isenabled to accommodate itself to soles of varying thicknesses.

By adjusting the supportingbar L toward or from the tip of the horn thedistance of the row of stitches from the edge of the welt may be variedas desired, and as the distance to which the edge of the welt projectsbeyond the upper depends upon the distance between the central portion,18, of the roll and the outer edge of the lower flange, 20, differentguiderolls are used for dilferentkinds of work, in which case the bar Lis adjusted to bring each roll into the exact position required withrespect to the tip of the born. The bar H and guide-roll M thus form asimple automatic device, by means of which the welt is held while beingsewed in the exact position required without any especial attention onthe part of the operator.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In a boot and shoe sewing machine, the combination, with a gage orrest for the edge of the welt and the upper of the boot or shoe, ot asliding bar, H, adapted to be brought down upon the welt, and having alongitudinal and lateral movement, substantially as described, forpushing or pressing the welt outward against the gage or rest andkeeping it constantly in contact therewith, as and for the purpose setforth.

2. In a boot and shoe sewing machine, the combination, with theworksupporting horn I) and stitch-forming devices, of the longitudinallyand laterally moving push -bar H, and the flanged guide-roll M, adaptedto form separate gages for the outer edge of the welt and the contiguousedge of the upper or vamp, whereby the welt is maintained at a uniformor unvarying distance from the vamp through out its entire length,substantially as and for the purpose described.

3. The sliding push-bar H, with its springp, adapted to be moveddownward in guides on the oscillating frame G by the contact with thespring'of a projection, m, and upward by the contact of aprojection, 12,with a projection, 13, thereon, in combination with the piece q, havingan inclined face, 16, whereby the lower end of the bar H is caused tomove obliquely to push the welt outward from the sole and keep itconstantly in contact with the inner portion, 18, of the gage-roll M,substantially as and for the purpose set forth.

4. The combination, with the horn D and the sliding pushbar H, of theguide roll M, with its central portion, 18, and upper and lower flanges,o w, mounted upon a supporting arm, L, made adjustable on theframe-work, substantially as and for the purpose described.

Witness my hand this 23d day of Jane, A. D. 1881.
